Maintenance Station Service Check
The maintenance station has two functions:
1. Cleans the printhead nozzles during the print operation.
2. Seals the printhead when it is not being used to prevent the
nozzles from drying.

Station Assembly
As the carrier moves to the right over the
maintenance station, a slot on the bottom of the
carrier engages a tab on the sled of the
maintenance station causing the cap to rise and
seal the printhead. Carrier movement to the left
uncaps the printhead. The wiper cleans the
printhead nozzles as the carrier leaves the
maintenance station. The wiper cleans the
printhead only when the carrier is moving to the
left. There should be no wiping action of the
printhead nozzles when the carrier is moving to
the right. After the cleaning operation is complete,
a tab on the maintenance station engages a tab on
the carrier, causing the wiper to lower.
Check the maintenance station for worn or broken
parts.
2
Wiper
Worn wipers cause degraded print quality just after
a maintenance cleaning. Check for loose or worn
wipers.
3
Cap
Worn caps cause the printhead nozzles to dry and
clog. Check for loose or worn caps.
